The agent channels

One catalog. Three channels. The same order.

The innovation is the agents. WhatsApp is where the customer is today.

One connector per merchant. Agent identity verified by signature.

The merchant's number. Katun operates it; never sees the card.

See detail
  • All three channels read the same catalog and close the same order; so does the bank's own assistant, through the same connector.
  • ChatGPT: OpenAI retired Instant Checkout in March 2026; payment closes on Katun's order page with the merchant's rail link. One app serves every merchant of the bank.
  • Claude: one MCP server per merchant; the owner approves exceptions in the console inbox.
  • WhatsApp: Meta-approved templates, specific-purpose bots, chat confirmation and the order in the console.
